Note that while there are people who are obsessed with light skin, there are also obsessed with tanned skin or natural brown skin. Countries like USA or the Red race are so obsessed with tanned skin. They do not even care when there skin is tanned under the sun.
However, getting tanned under the sun is not healthy. Heat brings cancer to the skin so if you want the natural way, better use products like lotions and the like because they are safer to use. If not the use spray products. Some of the tanning lotions include Beauty by Earth that is labeled with self Tanner.
Some will make the skin tanned in a natural way but some will will look artificial. This is why if you think that the product is not appropriate for you then better not take it. Some may even cause rashes on the skin perhaps because there are fake products or your skin is so sensitive so it is not possible for you to be using such.
Some will even make their skin tanned by too much amount of lotion. However, too much may not have a good result. This is why you must control the amount of lotion you rub on your body. It is better to make sure than no sure. Know the amount of tanning formula so that you know how to control your tanning. If you do not know, you might not find it effective or you will be tanned too much not according to what you like.
